Eliminate the need to carry two chargers, this adapter allows for concurrent charging of two separate devices! The charger adapter plugs directly into your existing mini USB wall charger or car charger (sold separately). An ideal charging solution if only one power outlet is available, now there's no need to swap devices on a single charger.
